In order to make the highest temperature of the battery lower than the temperature which can be endured by the material, excessive air needs to be introduced into the cathode, and the increased air compression and transportation consume extra energy, so that the overall power generation efficiency of the battery is reduced. The problem of non-uniform temperature is more obvious in a power generation system consisting of a cell stack and a plurality of stacks, and the large-scale application of the SOFC is severely restricted.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The high-temperature heat pipe rib connection plate of the solid oxide fuel cell proposed according to the embodiment of the present invention is described below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a high-temperature heat pipe rib connection plate structure of a solid oxide fuel cell according to an embodiment of the invention.
As shown in fig. 1, the high-temperature heat pipe rib connecting plate of the solid oxide fuel cell comprises: a metal plate and a plurality of heat pipes.
The heat pipes are fixed on the metal plate to form heat pipe ribs, and gas channels are formed between the metal plate and the heat pipe ribs for gas in the fuel cell to pass through.
The heat pipe is filled with liquid for heat exchange.
Specifically, the heat pipes are fixed on one metal plate in a welding mode to form heat pipe ribs, the number of the heat pipes welded on each metal plate and the distance between the heat pipe ribs can be changed according to requirements, and gaps formed between the metal plates and the heat pipe ribs are gas flow channels.
In fig. 1, heat pipe ribs are welded to one side of a metal plate, and an anode flow channel and a cathode flow channel of a fuel cell are separately provided.
As another embodiment, the anode flow channel and the cathode flow channel may be formed by welding heat pipe ribs to both sides of one metal plate.
As another embodiment, as shown in fig. 2, a connecting plate is formed by welding metal strips in sequence between heat pipe ribs, and the space between the heat pipe ribs is divided into an anode channel and a cathode channel by the metal strips, in this configuration, the cathode and the anode share a set of heat pipe ribs, and the shape of the anode channel and the cathode channel are the same.
Furthermore, in the actual working process, the heat pipe ribs are in direct contact with the porous anode on one side of the anode, the fuel gas enters from a flow channel formed by the porous anode, the heat pipe ribs and the metal plate, and is diffused into the porous electrode in the flowing process to generate electrochemical oxidation reaction and release heat. The heat pipe ribs in direct contact with the anode can rapidly conduct heat from the higher temperature region to the lower temperature region and collect the current from the anode. The metal plates may serve to further collect current and isolate anode and cathode gases. On the cathode side, the space surrounded by the porous cathode, the heat pipe ribs and the metal plate forms a cathode flow channel, and air diffuses in the flow channel to the porous cathode to generate electrochemical reduction reaction. The heat pipe ribs are in direct contact with the porous cathode, so that current can be collected, heat in a region with higher temperature of the porous cathode is conducted to a position with lower temperature, heat exchange with air is enhanced, and heat generated by more batteries can be carried away by air tail gas.
As shown in fig. 3, in the embodiment of the present invention, the high temperature heat pipe of the SOFC uses Na and K as the working liquid, the inside of the SOFC is divided into a vapor region and a liquid region, the internal cycle can be divided into three sections, and the liquid in the core of the high temperature region absorbs heat and evaporates into the vapor region, which is an evaporation section. The vapor flows to a region with lower temperature under the action of pressure, and can be regarded as not exchanging heat with the outside in the process, and the region is an adiabatic region. The vapor releases heat and is condensed into liquid after reaching the cold end, and the liquid enters the inner core, and the section is a condensation section. The liquid in the condensing section passes through the heat insulation section to reach the evaporating section under the capillary action, and the circulation is completed. The heat pipe exchanges heat by utilizing the phase change process of the working liquid, so that the heat pipe has good isothermal property and heat exchange performance.
In the embodiment of the present invention, the arrangement form of the heat pipe ribs is not limited to the parallel form in the above embodiment, the heat pipe ribs of the cathode and the anode may have an arrangement form of parallel, cross, serpentine, etc., the formed flow channel also has various configurations of parallel flow channel, cross flow channel, serpentine flow channel, etc., the arrangement form of the heat pipe ribs may be arranged according to the actual application, and the present invention is not particularly limited. As shown in fig. 4, the black part represents the heat pipe rib, and the white part represents the flow channel. The parallel flow channel is formed by placing a plurality of heat pipe ribs in parallel. The number and spacing of the heat pipe ribs may be adjusted to account for airflow distribution uniformity. A snake-shaped flow channel can be formed by arranging a series of parallel heat pipe ribs and the heat pipe ribs vertical to the heat pipe ribs, convection can be increased through the snake-shaped flow channel, heat exchange between gas and the heat pipe and between electrodes is enhanced, and concentration polarization brought by diffusion loss can also be reduced through convection enhancement. Snakelike runner structures with different runner widths, lengths and bending numbers can be designed by considering the factors such as pressure loss, fuel utilization rate and the like.
The high temperature heat pipe rib connecting plate and the principle of the solid oxide fuel cell of the present invention will be explained below by means of specific embodiments.
As shown in fig. 5, a plan structure diagram of the anode-side connection plate is shown, and the anode-side connection plate includes 11 horizontal heat pipe ribs and 2 vertical heat pipe ribs welded to a metal plate after casting, and the specific shape is a black part 1 in the lower drawing, and a white part 2 is a snake-shaped anode flow channel surrounded by the heat pipe ribs and the metal plate. The left lower part is a fuel inlet, the right upper part is a tail gas outlet, 12 zigzag structures are arranged in the flow channel, and the flow channel covers the whole porous anode.
The used fuel is hydrogen, the hydrogen enters the snake-shaped flow channel from the inlet at the lower left side of the connecting plate, and diffuses into the SOFC porous anode in the flowing process, electrochemical oxidation reaction occurs at the three-phase interface of the electrode, a large amount of heat is released, the generated high-temperature tail gas diffuses into the flow channel, the concentration of the fuel gas is gradually reduced in the flowing direction, the concentration of the tail gas is gradually increased, the gas temperature in the flow channel is continuously increased along with continuous heat exchange with the wall surface of the heat pipe, and finally the tail gas flows out through the outlet at the upper right corner and takes away the heat. In the middle area of the cell, the heat generated is greater and the heat conduction is poorer and therefore the temperature is higher, here the heat pipe evaporation section. Working fluids (such as sodium, potassium, etc.) are converted from a liquid state to a gaseous state, and a phase change process absorbs a large amount of heat. The gas temperature at the hydrogen inlet is lower, the fuel concentration is lower near the outlet, the electrochemical reaction strength is weaker, and the released heat is less, so that the inlet and the outlet are heat pipe condensation sections. Na vapor in the evaporation section is transported to the evaporation section and condensed into liquid from gas state, and a large amount of heat is released; the part in the transportation process is a heat pipe heat insulation section, wherein the heat pipe can be regarded as a heat insulation state, and does not absorb heat or release heat. The heat exchange capacity in the phase change process is strong, and the heat pipe has good heat exchange performance and isothermal performance. Different positions in the anode plane release heat and are not uniform, and the temperature difference of the SOFC caused by nonuniform heat release can be reduced through heat pipe enhanced heat exchange. Meanwhile, the highest temperature of the battery is reduced, and the situation that the battery is burnt through due to local hot spots is avoided. The arrangement of the serpentine flow channel can strengthen convection, the flow velocity is accelerated, the thickness of a laminar diffusion layer on the surface of the electrode can be reduced, fuel in the flow channel can be diffused into the porous electrode more quickly, and the concentration polarization of the SOFC is reduced; the heat exchange between the gas and the heat pipe can be enhanced while the convection is enhanced, more heat can be taken away by the tail gas at the outlet, and the average temperature of the battery is reduced. The snakelike runner can effectively cover the electrode surface, and electrode plane gas distribution is more even, and electrode three-phase interface active site utilization ratio improves, reduces the battery polarization loss. The serpentine flow channel simultaneously increases the residence time of the fuel gas and increases the fuel utilization rate.
If methane is used as the anode, the steam reforming reaction of methane is required to be carried out inside the SOFC, this reaction is endothermic, the internal reforming chemical reaction of methane mainly occurs at the cell inlet, and the electrochemical reaction intensity is low, so the temperature at the inlet is low, most of methane at the rear part of the stack has been converted into hydrogen and carbon monoxide, the reforming endothermic reaction is weak, and the electrochemical reaction exotherm is strong, so the temperature is high. At this time, the methane inlet is a condensation section of the heat pipe rib, and the middle rear part of the battery is an evaporation section of the heat pipe rib. The heat pipe rib connecting plate can reduce the problem of overlarge temperature gradient in the methane internal reforming SOFC, and the internal reforming reaction is introduced into the cell stack to effectively absorb the electrochemical reaction heat, so that the total heat release of the cell is reduced, and the heat management of the cell is facilitated.
As shown in fig. 6, the planar structure of the cathode-side connection plate is shown. The heat pipe comprises 9 vertical heat pipe ribs and 2 horizontal heat pipe ribs, wherein the vertical heat pipe ribs and the horizontal heat pipe ribs are welded on a metal plate after pouring, the specific shape is a black part 1, a white part 2 is a snake-shaped flow channel structure formed by the heat pipe ribs and the metal plate in a surrounding mode, and the structure has 7 meanders.
One end of the air of the cathode is designed to enter from the inlet at the left lower side of the connecting plate, and the tail gas flows out from the outlet at the right lower side. To reduce the pressure loss of the cathode excess air, the cathode flow channel width is larger than the anode and the serpentine structure is smaller than the anode. Cathode air flows into the serpentine flow channel from the inlet, diffuses into the porous cathode during the flow process to undergo electrochemical reduction, oxygen is consumed during the process, and the cathode gas flow is reduced. And in the flowing process, the heat exchange is continuously carried out with the heat pipe ribs, the temperature is continuously increased, and finally the heat flows out from the lower right side of the connecting plate to take away a large amount of heat generated by the SOFC. The heat pipe ribs are in direct contact with the porous cathode, the temperature of the middle part of the electrode is highest, the temperatures of the two sides of the electrode are relatively low, and the heat of the middle part is dispersed to the two sides by the heat pipe ribs.
According to the high-temperature heat pipe rib connecting plate of the solid oxide fuel cell provided by the embodiment of the invention, the plurality of heat pipes are fixed on the metal plate to form the heat pipe ribs, a gas flow channel is formed between the metal plate and the heat pipe ribs for gas in the fuel cell to pass through, and the liquid is filled in the heat pipes for heat exchange. The high-temperature heat pipe rib connecting plate structure of the solid oxide fuel cell consisting of the heat pipe ribs enhances the internal heat exchange capability of the SOFC cell sheet and improves the thermal shock resistance of the cell.
